This site focuses on an existing method of geo-engineering — rain-making. Proven abilities to make rain are more than 50 years old. There are wide differences in beliefs on effectiveness, and it is not the intention to debate that. It does intend to catalogue events for comparison on outcomes and, more importantly, to avoid potential conflict from rain-making activities that may have international implications or the perceptions of them.
